Abstract (en)
A method for controlling a renewable energy power system having at least one renewable energy asset connected to a power grid during a frequency event includes receiving, via a controller, a frequency signal of the power grid. The method also includes determining a time constant for a frequency filter assembly as a function of two or more parameters of the frequency signal. Further, the method includes filtering the frequency signal via the frequency filter assembly using the determined time constant. Moreover, the method includes determining a power command for the at least one renewable energy asset using the filtered frequency signal. In addition, the method includes controlling the at least one renewable energy asset based on the power command.
